Welcome to my Metazoic site! This site discusses the existence of the creatures to come along after humans will be extinct. I first became interested in a world after man when I acquired my first copy of Dougal Dixon's After Man: A Zoology of the Future in 1992. However, I unwittingly created creatures that did not exist from the time I was about 8 years old. But it was after I obtained a copy of that book (now a collector's item) that I decided to take these same creatures I created as a child and make them more realistic in an evolutionary sense. Though it may be hard for a lot of us to grasp, humans will soon become extinct. One of the biggest factors of how this will happen is the current overpopulation rate. Which is why I don't contribute to the population. I created this world with little more than mammals fulfilling all ecological niches with the help of some friends. I even gave the era of the age after man a name, I called it the Metazoic, derived from the words for "After-era" (Meta, meaning after, and zoic meaning era). We are now in the Cenozoic era. To view all the animals I have created since I began this project, you can go to the "Meet the Mammals" section of this site. To discuss your own ideas about what you think will happen in the future world, and share your ideas with others, please feel free to leave a comment. One more thing, some of you may find this site quite offensive, and you have a right to your own opinion. But please respect my right to have an opinion too. I'm not saying there is no GOD, I believe it was HIM who got the ball rolling. But I believe after that, evolution took over. There is so much more evidence of evolution than there is of creation. Even that going on right under our noses. Other than that, enjoy yourself and visit our many links.

Extinction Caused By Toxic Gases

So many people have wondered what caused the extinction after the Permian period that took out almost all living things at that time. I think even I have posted several articles about this subject. It is probably one of the most controversial topics in biological science. But this article I found was interesting in that it discusses another idea of what ended the Permian period. Their idea was volcanic gases.

Feb. 4, 2009 -- An ancient killer is hiding in the remote forests of Siberia. Walled off from western eyes during the Soviet era and forgotten among the endless expanse of wilderness, scientists are starting to uncover the remnants of a supervolcano that rained Hell on Earth 250 million years ago and killed 90 percent of all life.Researchers have known about the volcano -- the Siberian Traps, for years. And they've speculated that the volcanic rocks, which cover an area about the size of Alaska, played a role in runaway global warming that led to the end -- Permian mass extinction, the worst dying the planet has ever seen.

Now a team of researchers led by Henrik Svenson of the University of Oslo in Norway have performed a series of experiments, showing the volcano employed an arsenal of deadly weapons during its 200,000-year-long assault on the biosphere.

Prime among them was carbon. Searing magmas from the volcano intruded into the Tunguska Basin in eastern Siberia, a region laden with thick deposits of coal, oil and gas. Heat from the molten rock baked the hydrocarbons, turning the area into the world's largest fossil fuel-burning plant. In all, the volcano may have belched as much as 100,000 gigatons of carbon into the air (all of humanity emits about eight gigatons of carbon annually).

That's more than enough to cause a global climate apocalypse. But the team also wanted to know what happened when lava infiltrated the area's abundant salt deposits. When heated in a laboratory to 275 degrees Centigrade (527 degrees Fahrenheit), the salts released a host of toxic gases, chief among them methyl chloride, an efficient ozone-killer.

"This is the first geologically realistic evidence that ozone collapse during the end-Permian could have actually happened," Svenson said.

But there is still a lot of uncertainty surrounding the findings, Linda Elkins-Tanton of the Massachusetts Institute of Technology said.

"There is evidence of a large number of genetic mutations in the fossil record around this time," she said, which could be the result of an onslaught of ultraviolet radiation due to a weak ozone layer. "But the idea of ozone destroyers is pretty new. The question is whether or not the eruptions were powerful enough to inject gases into the stratosphere."

The answer may come from close examination of hundreds of pipe-like structures strewn throughout the Tunguska Basin. Often 300 meters (984 feet) in diameter, Svenson's team believes the pipes are ancient volcanic craters left over after the lethal mix of carbon and chlorine gases exploded into the atmosphere.

Well, you don't need to apologize. I don't think it's your fault. I just find these articles and print them here. This one is actually from yesterday. And I've probably printed one like it here before. But thank you for telling me.
